4. INTRODUCTION (PROJECT DESCRIPTION,OBJECTIVES AND SCOPE)

5. PROJECT OBJECTIVES The main objective of this project is to successfully plan, design, and construct a two-storied reinforced cement concrete (RCC) residential building in Dhaka, Bangladesh. The project aims to deliver a safe, durable, cost-effective, and aesthetically pleasing residential structure that meets the modern housing needs of an urban family. Key goals include: Ensuring timely completion of construction activities within a span of 10 months (approximately 300 days). Maintaining the total project cost within the allocated budget of BDT 36 million. Achieving quality construction outcomes by using best practices in materials, workmanship, and planning.

6. PROJECT OBJECTIVES(Cont’d) Ensuring full compliance with relevant regulatory authorities, specifically adhering to RAJUK (Rajdhani Unnayan Kartripakkha) and BNBC (Bangladesh National Building Code) standards. Incorporating sustainable construction methods and the use of locally available materials to promote environmental responsibility.

7. SCOPE OF THE PROJECT The scope of the project encompasses the complete development of a two-storied residential structure including civil, structural, electrical, plumbing, and finishing works. Key inclusions: Total construction area of approximately 7,600 square feet, split into two floors (~3,663 sq. ft. each). Layout and provision for all essential household spaces: multiple bedrooms, bathrooms, a kitchen, living room, dining space, and service areas. Execution of civil and structural works, including foundations, superstructure (RCC frame), and masonry.

8. SCOPE OF THE PROJECT(Cont’d) Installation of MEP (Mechanical, Electrical, and Plumbing) services, including modern wiring, plumbing lines, water supply, and sanitary fittings. Full interior and exterior finishing, including tiling, flooring, painting, door/window fittings, and false ceiling (if required). External development, such as boundary walls, main gate, landscaping, and driveway construction. Preparation of planning documents, including a Work Breakdown Structure (WBS), Gantt chart, bar chart, and cost estimation plan. Ensuring the handover process, which includes final inspection and client approval.

9. MAJOR COMPONENTS OF THE PROJECT The project has been broken down into the following major components to ensure systematic implementation: Site Preparation Substructure (Foundation Works) Superstructure (RCC Frame) Masonry and Plastering Flooring and Tiling Doors and Windows Plumbing and Sanitary Installations Electrical Wiring and Fixtures

10. MAJOR COMPONENTS OF THE PROJECT (Cont’d) Painting and Finishing Works External Development

11. ASSUMPTION To ensure smooth project execution, the following assumptions have been made: The project site has been legally acquired, and there are no land disputes or legal hindrances. Soil conditions are stable and verified through geotechnical testing, ensuring foundation design safety. Necessary approvals and permits (RAJUK, BNBC, utility services) will be obtained without significant delay. Labor availability is consistent throughout the project period, and required skill levels are accessible.

12. ASSUMPTION (Cont’d) All construction materials (cement, steel, bricks, tiles, etc.) will be locally available and delivered on time. No major design modifications will be requested after construction begins, helping avoid scope creep. Adequate financial resources will be available throughout the project to avoid funding delays. Weather conditions will permit uninterrupted outdoor construction work for most of the year.

13. CONSTRAINTS While planning and executing the project, several limitations must be acknowledged: Time Constraint: The construction must be completed within a strict 10-month timeline, including planning, approvals, and execution. Budget Constraint: The total cost is capped at BDT 36 million, requiring tight cost monitoring and budget control throughout the project. Regulatory Compliance: Adherence to RAJUK guidelines and BNBC codes is mandatory, limiting flexibility in design or materials. Urban Site Challenges: Limited space for material storage, machinery movement, and waste management due to the congested Dhaka location.

14. CONSTRAINTS (Cont’d) Weather Dependence: Monsoon season in Bangladesh may cause work delays, especially during excavation, concreting, or external development. Labor and Resource Risk: Potential risks of labor strikes, shortage of skilled workforce, or material price fluctuations. Client Change Requests: Any late-stage design or material change requests can disrupt the construction schedule and increase costs. Safety Regulations: All work must comply with worker safety norms and on-site accident prevention protocols.

15. WORK BREAKDOWN STRUCTURE (WBS)

16. The Work Breakdown Structure (WBS) is developed by systematically breaking down the overall project scope into smaller, manageable components. It starts with a clear understanding of the scope, as defined in the project scope statement. Major deliverables or phases are first identified, forming the top level of the WBS. It is typically presented in a hierarchical format, such as an indented list or tree diagram.

17. BENEFITS OF WBS Breaks down the overall project scope into smaller, manageable components. Begins with a clear understanding of the project scope statement. Identifies major deliverables or phases at the top level. Presented in hierarchical format (indented list or tree diagram). Clarifies what needs to be done by an organization or subcontractor. Facilitates responsibility assignment. Enables effective progress tracking

18. Drawbacks OF WBS Requires significant effort to create for complex project. Too many small tasks can make management cumbersome. . Difficult to adjust when project scope changes. . Poorly defined tasks can cause confusion and rework . May overlook process-oriented activities . Inaccurate scope leads to flawed WBS . Lacks timelines, dependencies, and resources without other tools.

19. ACTIVITY DEFINITION AND SEQUENCING

20. INTRODUCTION A project activity is a distinct task or work function where a particular worker or crew of workers completes a specific item of work within a prescribed time frame. The “job” must be measurable for each project activity. The Work Breakdown Structure (WBS) for the two-storied RCC residential building is divided into four major components—Substructure, Superstructure, MEP (Mechanical, Electrical, Plumbing), and Finishing Work —each of which can be further broken down into progressively detailed levels.

39. CONCLUSION

40. PROJECT RISKS Weather delays: Heavy monsoon rains in Dhaka can significantly delay excavation and concreting. Material price fluctuation: Unforeseen increases in the cost of steel, cement, or bricks can impact the budget. Labor shortages: A lack of skilled workers or strikes can cause project delays. Design changes : Changes requested by the client during construction can disrupt the schedule and increase costs.

41. CONCLUSION This project report outlines a comprehensive plan for the construction of a two-storied RCC residential building. By adhering to the proposed schedule, managing the budget, and proactively mitigating identified risks, the project can be completed within the 10-month timeframe and the ৳36 million budget, delivering a quality residential building in Dhaka, Bangladesh. We converted this plan into contract documents, and we prepared a detailed BOQ, obtained vendor quotes, performed geotechnical investigation, and finalize the structural and MEP designs (to align quantities with cost and schedule precisely. The attached schedule, Gantt chart, and bar chart provide concrete tools for daily/weekly tracking and risk monitoring.
